This visualization shows the population of 20 countries in the year 2010 as a horizontal bar chart. The bars are rendered as SVG rectangles using React components, with the x-axis scaled linearly and the y-axis using a band scale for country names. The code uses D3 v5’s `scaleBand`, `scaleLinear`, `max`, and `format` for axes and tick labels, while the dataset is loaded via `d3.csv` from a GitHub URL. A simple tooltip is provided through SVG `<title>` elements showing the formatted population value.

Question1(2)

This horizontal bar chart shows population figures for 20 countries in 2010, with each bar’s length representing the population value and country names listed on the vertical axis. The visualization uses React components to render SVG elements, with d3.scaleBand for the categorical y-axis and d3.scaleLinear for the numeric x-axis. Population values are formatted using d3’s format function, converting units to billions with the letter B. Data comes from a CSV file loaded via d3.csv, and hover tooltips display the exact formatted population using SVG title elements.

Question 1 part 2

This bar chart displays the population of 20 countries in 2010, with countries listed on the vertical axis and population values on the horizontal axis. The visualization uses React components to render SVG elements, with d3.scaleBand and d3.scaleLinear for positioning and scaling. Data is loaded asynchronously from a CSV file via d3.csv, and tick formatting converts large numbers using d3.format. The bars include native SVG title elements for tooltips showing the exact population values.

Question-1.2 Task-1

This horizontal bar chart displays the population of 20 countries in 2010, sorted by country name. The visualization uses React with D3.js scales and axes to render SVG rectangles, with bars sized proportionally to population values. The code imports D3’s `scaleBand`, `scaleLinear`, and `format` APIs, while loading data via `csv` from a GitHub-hosted CSV file. Tooltips show formatted population values using a custom tick format that shortens large numbers to billions.

Question 1.2

This chart shows the populations of 20 countries in 2010 as horizontal bars. React and D3 v5 are used to render an SVG visualization, with a band scale mapping countries to the y-axis and a linear scale for population values. Data is loaded from a remote CSV using `d3.csv`, and D3’s `scaleBand` and `scaleLinear` drive the layout, while `d3.format` with the `.2s` specifier formats tick labels and tooltips. Axes and marks are defined as React components, with custom tick styling for lines and text.

Question-1.2

This horizontal bar chart displays the population of 20 countries in 2010, with bars extending rightward from a shared left origin to represent each nation’s total population. Built with React and D3 v5, the visualization uses `scaleBand` for the categorical country axis and `scaleLinear` for the population scale. Rectangular marks are rendered as SVG elements, and the D3 `format` function abbreviates axis tick labels (e.g., converting millions to “B”). Data is loaded asynchronously via `d3.csv` from a GitHub-hosted CSV file.

Question_1(a)

This bar chart displays the population of the top ten countries in the year 2000, using horizontally-oriented rectangles. Built with React and D3 v5, it employs `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. The SVG rendering includes custom axis components and a tooltip that formats population values using `format('.2s')`. Data is loaded asynchronously from a remote CSV file via a custom `useData` hook that uses `d3.csv`.

Question 2

This bar chart visualizes the population of 20 countries in 2010, sourced from a CSV file. The chart uses React with SVG rendering, leveraging D3 v5 APIs like `scaleBand` and `scaleLinear` for positioning. Horizontal bars are drawn with `rect` elements, with axes generated by custom components using D3’s `ticks` method. Population values are formatted with `d3.format`, converting values to billions, and a native SVG `<title>` element provides tooltips on hover.

Question 1.2

This visualization displays the populations of the top 20 countries in 2010 as a horizontal bar chart, using a linear x-scale for population values and a banded y-scale for country names. The chart loads CSV data from a GitHub repository and renders bars as SVG rectangles with native tooltips. Built with React and D3 v5, it uses `scaleLinear`, `scaleBand`, `csv`, and `format` to process data, compute scales, and format tick labels. The axes are custom React components that generate `line` and `text` SVG elements.
